Group,
Sendmail.org has released sendmail 8.13.7. I see nothing in there that
should/would cause any issues for MIMEDefang, except for one overlapping
feature between the two packages. The sample mimedefang-filter.example sets
"$MaxMIMEParts = 50", where if I'm reading the sendmail release notes
correctly, sendmail 8.13.7 now sets this limit at 20...
8.13.7/8.13.7 2006/06/14
A malformed MIME structure with many parts can cause sendmail to
crash while trying to send a mail due to a stack overflow,
e.g., if the stack size is limited (ulimit -s). This
happens because the recursion of the function mime8to7()
was not restricted. The function is called for MIME 8 to
7 bit conversion and also to enforce MaxMimeHeaderLength.
To work around this problem, recursive calls are limited to
a depth of MAXMIMENESTING (20); message content after this
limit is treated as opaque and is not checked further.
Problem noted by Frank Sheiness.
In the sendmail source tree for 8.13.7, I found MAXMIMENESTING defined in
sendmail/conf.h.
David, would this "opaque remaining content" present a problem for
MIMEDefang?
